Vanadium

Vanadium was discovered in 1801 by the Spanish scientist Andres Manuel del Rio. Del Rio discovered the new element in brown lead ore (now known to be the mineral vanadinite, Pb 5 [VO 4] 3 Cl) in New Spain (Mexico).. Del Rio had moved to Mexico as a professor of Chemistry and Mineralogy at the Royal School of Mines, Mexico City.
